Baxi Condensate Trap Replacement Kit 5111978

A Baxi condensate trap collects condensate discharge created inside the boiler’s primary heating system. As pressure and temperature fluctuate, water builds up in the trap and exits through a discharge pipe, helping prevent internal leaks and protecting safe operation.

Because carbon dioxide from the combustion process can dissolve into this water, condensate may be mildly acidic. That’s why the discharge pipe is almost always made from plastic, which handles condensate safely.

If your condensate trap is leaking, blocked, or damaged, replacing it with the correct Baxi condensate trap kit is often the most reliable fix. This replacement kit is designed to restore proper condensate flow and reduce the risk of boiler shutdowns caused by drainage issues.

Frequently Asked Questions (FAQs)

1. How do I clean a Baxi condensate trap?
Cleaning usually involves isolating the boiler safely, removing the trap, rinsing out debris, and refitting correctly. If you’re unsure, use a Gas Safe engineer-incorrect refitting can cause leaks or faults.

2. Why is my Baxi condensate trap leaking?
Common causes include a cracked trap body, worn seals, poor refitting, or a blockage causing overflow. If the trap or seals are damaged, replacing with a Baxi condensate trap replacement kit is typically the best solution.

3. How do I remove a Baxi condensate trap?
Removal varies by model, but normally the boiler must be safely isolated first. The trap is then detached from the condensate pipework and mounting point. A Gas Safe engineer is recommended to avoid leaks and ensure correct reassembly.

4. How much does it cost to replace a Baxi condensate trap?
Costs depend on your boiler model and local labour rates. The part cost is fixed, but labour can vary based on access and whether cleaning or additional pipework checks are needed.

5. Can I replace the condensate trap myself?
If you’re not Gas Safe registered, it’s safer to use a qualified engineer. Even though the trap is part of the condensate system, incorrect installation can lead to leaks, fault codes, or damage to the boiler.
